One option would be donk yourself on turn and make him a surprised. Or do you expect him to barrel with air or something similar as 2nd barrel? What's his CBet flop/CBet turn? But if he is a reg then I guess he is as well capable of laying down his TP type of hands even here. Might just donk myself on turn and maybe even would keep TP type of hands in the range or something like Check/Call and donk the river. Really depends on the opponent how he does understand our play.

Yes the problem was that I had only 40-60 hands on the opponent so I didn;t know him very well . Now I think x/c turn would be better than donk because if we donk we show strenght so he wouldn't call us again very easy on the river . On the other side with x/c turn and donk or x/raise on river we are more likely to extract value - with donk he would bluffcatch sometimes and with check we enable him to do one more valuebet .
